ADJUSTABLE HEAD-GATE.

Specification of Letters Patent. Patented F eb. 22, 1916,

Application filed April 9, 1915. 7 Serial No. 20,225.

To all whom it may concern:

Be it known that I, JOHN H. BOGARD, a citizen of the United States, residing at San Saba, in the county of San Saba and State of Texas, have invented a new and useful Adjustable Head-Gate, of which the following is a specification.

The present invention relates to improvements in head gates, one object of the invention being the provision of an adjustable gate adapted to be used in connection with irrigation ditches, the. gate being so constructed as to be readily moved from place to place and to be presented across any portion of the ditch, the gate being laterally adjustable to. accommodate the same to varying widths of ditches, and. being provided with means for locking the sections of the gate extended. V

A further object of the present invention is the provision of a gate of this character provided with a handle carried member which in turn constitutes a supportfor the laterally movable wings or sections of the gate, vertically sliding means being provided for controlling the extension or col lapse of the sections or wings so that the same may be operated either through foot or hand power as desired.

A further object of the present invention is the provision of a gate of this character, which is simple, inexpensive and durable in construction, and thoroughly eflicient and practical in use.

With the foregoing and other objects in view which will appearas the' description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed with-. out departing from the spirit of the invention.

In the drawings, Figure 1 is an elevation of the present device viewed from the operating side thereof. Fig. 2 is an edge view of the device as illustrated in Fig. 1. Fig. 3 is a view similar to Fig. 1 but showing the opposite side of the gate. Fig. 4: is a top plan ofthe gate as illustrated in Fig. 1, the

operating handle being shown in section.

Fig. 5 is a section taken on line 5-5 of Fig. 1. Fig. 6 is an enlarged detail perspective of the pawl and locking means for holding the sections extended. 7

Referring to the drawings, the numeral 1 designates a verticalv strip or plate which constitutes the carrying member for present gate, the strip being provided at one end with a pointed earth entering prong 2, and

7 being equipped with two straps or bands 3 at the opposite end which are adapted to recelve an operating handle or helve 4:. Attached by means of a rivet 2 or other fastening device to the side of the entering prong 2 of the member 1 is a plate 2, which constitutes a guiding means for the sections 7 and 7' of the gate. Connected to the member 1 and located upon the same side thereof as the guiding member 2 is a headed pin 5, which is received in slots 6 and 6 fashioned in the gate sections 7 and 7, so that the gate sections will be permitted straight line lateral movements to and from each other to admit of the collapse or extension of the gate, the lower edges of the sec- 10113 7 and 7- being guided in the mem- The outer and the lower edges of the sec-- tions 7 and 7 are strengthened by means of a reinforcement 8. Cooperating with each section is an auxiliary gate '10, which is mounted for sliding movement in a frame 9. By this means the size of the opening controlled by the auxiliary gate 10 may be regulated to permit any desired flow of water through the present head gate when the same is in place in the ditch.

Slidably mounted in cleats 11- and 11 upon the carrying member 1 and disposed upon the side opposite to the guiding mem ber 2 is a plate 12, the same being mounted for longitudinal movement relatively to the member 1. The plate 12 is provided with a foot operating offset 13 upon its lower end and with a hand operating offset 14 at its upper end.

. Links 17 are pivotally connected as shown at 50 with the plates 7 and 7, links 18 being pivotally connected as shown at 51 with the plates 7 and 7. The links 17 andlS are'provided with longitudinal slots '52 having lateral extensions 53. A headed pin 15 enters the member 12 and is adjustable in the slots 52 of the links 17,:the pin 15 being adapted to be engaged in any pair of extensions 53 of the links 17. A pin 16 is carried by the member 12 and is received in the slots 52 of the links 18, the pin being adapted to be lodged in any pair of the extensions 53 of the links 18. Theinner ends 1 tions or toward each other to widen the gate in the one instance or to decrease the width thereof in the other. The pins 15 and 16 may beengaged in any of the slot extensions 53 to vary the effective length of the links, the links being provided with handles 5 1 which facilitate a shifting of the positions of the links with respect to the pins 15 and 16.

In. order to provide a means for locking the member 12 in its lowest position when the sections 7 and 7" 2 having been pushed into the earth. at the bottom of the ditch, a longitudinal slot 19 is formed in the member 12, one edge 01""- the slot being provided with ratchet teeth 20 disposed. in cooperable relation with a pawl 21, said. pawl 21 being pivoted at 22 to the member 1 and being provided with a weighted end. 23 which/normally holds the locking end 21 against the teeth 20. The pawl 21 may be released manually so that the member 12 may be moved toward the handle 4 to collapse the section 7 and 7.

From the foregoing description, it is evident that a gate constructed according to and embodying the present invention, is portable, and may be readily carried from place to place, and be manipulated similarly to a shovel, in that the handle at may be so operated to place the entering point 2 at the center of the ditch, with the wings or sections 7 and 7 transversely of the ditch, it merely being necessary to push the operating member 12 either by foot or hand downwardly to extend the sections 7 and 7 so that the outer edges thereof and the bottom portions will be placed in engagement withthe outer edges or walls and the bottom of the ditch.

By reason of the fact that the pawl and ratchet device locks the member 12 in its downward position, the sections 7 and 7 are thus held extended with the marginal edges thereof entering the earth at the bottom and. side walls of the ditch while the entering point 2 anchors the device at its lowermost point.

What is claimed is:

1. In a device of the class described, a carrying member; gate sections mounted to slide transversely of the carrying member; an actuating element mounted to slide longitudinally of the carrying member; means for holding the actuating element'in adjusted positions on. the carrying member; links pivoted at their outer ends to the gate are extended, the prong.
